Specification of Letters Patent.

Patented Jan. 22,1907.

Application filed March 21,1906. Serial No. 307.242.

To all whom it may concern.-

Be it known that we, OSCAR CLARENCE BEACH and ARTHUR L E BUzzELn,citizens of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented certain new anduseful Improvements in a Combined Pulverizer and Sampler; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked there on,which form a part of this specification.

This invention relates to new and useful improvements in apparatus forpulverizing frangible material and simultaneously quartering the same,if desired; and the object of the invention is to produce a machine inwhich the grinding-plates are held in horizontal planes, one of which isvertically adjustable, being held by means of a knucklejoint havingsuitable ball-bearings and so arranged that the grinding-surfaces may beadjusted for any degree of fineness.

The invention consists in various details of construction andcombinations and arrangements of parts, as will be hereinafter fullydescribed and then specifically defined in the appended claims.

We illustrate our invention in the accompanying drawings, in whichFigure 1 is a perspective view of our invention. Fig. 2 is a verticalsectional view centrally through the apparatus. Fig. 3 is a perspectiveview of a receptacle for receiving the pulverized material, and Fig. 4is a detail view showing the dividing-cups positioned therein.

Reference now being had to the details of the drawings by letter, Adesignates a standard made, preferably, of metal and supports a hopperB, which is tapering, and to the lower end of said hopper is fastenedone of the stationary grinding-plates C, which has a central openingwith a tapering marginal wall to said opening. D designates ashaft whichpasses centrally through said opening and is mounted vertically andpasses centrally through said opening. A grindingdisk E is fixed to thelower end of said shaft and has upon its upper surface a tapering ointportion E, which is corrugated and adapted to conform to the taperingmar in of the opening in the grinding-plate C. aid shaft, which ismounted in suitable bearings in the frame of the apparatus, has swiveledto its upper end a threaded ro'd F, having ballbearin s, and to said rodis pivotedaknucklewhich is designed to engage the slot A, formed in theoverhanging portion of the frame of the apparatus. An adjusting-nut H ismounted upon said knuckle-joint Cr and is adapted to bear against theupper end of the frame, as shown clearly in the drawings,

whereby the shaft may be held in an adjusted position. An adjusting-nutI is mounted upon said threaded rod, which has swiveled connection withthe shaft, and a jam-nut J is also mounted upon thethreaded portion ofsaid rod and is adapted to bear against the adjusting-nut I. Fixed tosaid shaft is a gear-wheel L, which is adapted to mesh with a bevel-gearN within the casing O, said gear N being fixed to the shaft N, which isj ournaled in suitable bearings in the frame of the apparatus. Abalance-wheel M is fixed to the end of the shaft N and is provided witha handle M.

Projecting from the opposite marginal edges of the flange about thelower end of the hopper are two screws Q, and R designates a receptaclewhich may be of any size, but which in the drawings is shown as having atapering circumference, and S S designate ears upon said receptacle,having slots S re versely arranged, said slots being provided to receivethe screws upon the flange at the lower end of said hopper, andretaining-nuts T are mounted upon said screws, whereby the receptaclemay be held in place. W W designate quartering-cups, which when placedtogether in the manner shown in the drawings have, their outer convexedcircumference of conical shape adapted to conform to the taper of saidreceptacle and in which they the receptacle, thereby causing thematerial being pulverized to be divided into four equal parts forsampling purposes. X designates a cover to said hopper, having anopening X formed therein, and Y designates a lid hinged to said coverand adapted to close over said aperture, whereby material may be fedinto the hopper. 1

rest and completely fill the lower portion of lated to the degree offineness at which it is desired to have the mineral reduced by simplyraising or lowering the shaft by means of the adjusting-nuts, which willcause the two plates to be nearer together or farther apart, as may bedesired. The pulverized material falling through the aperture in thestationary plate is thrown out by centrifugal force between the twoplates and falling into the re ceptacle beneath is equally distributedinto the quartering-cups for sampling purposes.

When it is desired to separate the grindingplates sufiiciently to allowthe same to be cleansed or for other purposes, the adjustingnut at thetop of the knuckle-joint may be loosened and the knuckle-joint swun outof the slot at the top of the frame, and t e shaft will lower bygravity, giving access to the wheels after the receptacle has beenremoved by first taking oif the adjusting-nuts which hold thereceptacle, said receptacle being removed by imparting a slight rotarymove- 'ment to the same suflicient to free the slotted ears from thescrews.

From the foregoing it will be observed that by the provision of theapparatus shown and described a simple and efl icient means is affordedfor reducing minerals to any degree of powdered state by the simpleadjustment of the nuts, regulating the distance between the twogrinding-plates, and so constructed that easy access may be had at anytime to the grinding-plates for cleansing or other purposes, while thereceptacle fastened to the hopper and provided with its quartering-cupsaffords means whereby the product may be divided into equal parts forsampling purposes.

What we claim is 1. An apparatus for pulverizing and dividing frangiblematerials, comprising a frame having a laterally-extending arm which isprovided with an open slot, a stationary grinding-plate having anopening therein, a screw positioned in said slot and provided with ahead at its lower end, a nut mounted upon said screw and resting uponsaid slotted arm, a vertically-mounted shaft swiveled to said head, agrinding-plate fixed to the bottom of said shaft, and means for rotatingthe latter, as set forth.

2. An apparatus for pulverizing and dividing frangible materials,comprising a frame, a stationary grinding-plate having an openingtherein, a hopper, a vertically-adjustable shaft, means for supportingthe same, a grinding-plate fixed to the bottom ofv said shaft, screwsprojecting from the flange of said hopper, a receptacle having ears withoppositely-disposed slots therein adapted to receive said screws, nutsupon said screws for holding the receptacle in place, and dividingcu swithin said receptacle, as set forth.

n testimony whereof we hereunto affix our signatures in the presence oftwo witnesses.
